D-Torch with quartz outer tube & installation guide, requires choice of injector. Compatible with Spectro SOP ICP-OES.A patented, precision-engineered, demountable torch, with a replaceable quartz outer tube. Since the quartz outer tube is usually the first to wear and can be replaced, the D-Torch provides a much lower operating cost than other demountable torches. It also incorporates a more robust ceramic inner tube and has the same mounting system as the standard fixed torch. Additionally, the D-Torch features interchangeable injectors, allowing flexibility in the installation of method specific injectors, whether it be for aqueous (~2.0mm ID), organics (<2.0mm ID), high TDS (>2.0mm ID) HF (alumina) or high purity (sapphire).
